 ## Bug fixes

 - fixed: MSW: File System Workspace: use ignore-case for file comparison when attempting to locate file in the tree view
 - Rust (remoty) - do not attempt to guess the current working directory, just use the workspace path as the root
 - [CppCheck crash][32]
+- [On Windows, use native toolbar for the side bar control][33]
+- Fixed: editor flickers after foramtter execution
+- SpellChecker: instead of parsing the line based on position, use Line + Col approach - this way, if we have offset error, it will only affect the current line
+  dnd the offset error will not get carried over to the next line.
+- SpellChecker: use `UTF8Lengh()` method to calculate real length of tokens, this should fix problems when using non ASCII chars in the document
+  and the spelling error marker does not correctly mark the word
+- [Language Server Diagnostics are not shown anymore since 17.9.0][34]
+- Fixed: spellchecker highlights sometimes are not aligned with the editor text
+- Fixed: there is a noticable lag when typing while the function argument tooltip is shown
+- Fixed: when the function arguments tip window shows, skip the first argument if it is "self" (e.g. for class method in `Python` or `Rust`)
+- Fixed: when LSP tries to place many markers ("diagnostics") on the editor, it causes an excessive reads from the disk which can cause a noticable lag
+- Editor navigation bar: remove the "bookmark" button (it causes too much extra work for CodeLite with no real benefit)
+- Fixed: Rust: the configuration option "Hitting ENTER in a C++ comment adds '//'" does not work Removed un-needed log line entry
+- Navigation control (Ctrl-Tab popup window) is now centered on CodeLite, regardless of its parent book
+- [Fixed: closing a modified tab on Linux / macOS causes to lose modified changes][35]
+- Fixed: some LSPs return completions that start with a ".", remove it before inserting it
